To avoid resending an email announcement about a new shoe to gold tier members who were informed last week, the marketing associate at Cloud Kicks should use the customer base data extension as the target audience and exclude the gold tier data extension from the send. This approach ensures that the communication is sent to the entire customer base except for those who are part of the gold tier segment, preventing overlap and redundancy in messaging to the gold tier members.
This targeted and exclusionary strategy is a best practice in email marketing, allowing marketers to finely tune their audience segments to deliver relevant and timely content without unnecessary repetition to certain groups.
